Abstract
The present invention is embodied in a method and system for customizing a visual sensor for facial feature tracking using a neutral face image of an actor. The method may include generating a corrector graph to improve the sensor's performance in tracking an actor's facial features.
Claims24
A method for customizing facial feature tracking, comprising:
- capturing a front neutral face image of an actor;
- automatically finding facial feature locations on the front neutral face image using elastic bunch graph matching;
- automatically positioning nodes at the facial feature locations on the front neutral face image of the actor;
- and
- manually correcting the positioning of the nodes on front neutral face image of the actor.
